“…The spiky spread of ZIKV throughout Americas [7], especially in Brazil, poses phobia for travelling to these countries and some travel restriction was put especially for pregnant females [4,26]. In our study, more than one-third of the participants believed that it will dangerous to travel to the countries where ZIKV is circulating.…”

“…In January 2017, The WHO reported that 75 countries around the world notified the continuing of ZIKV mosquito-borne transmission, and 46 of these countries are in the Latin American and Caribbean territories. The virus has recently spread throughout the whole Americas [6,7]. ZIKV continues to spread geographically to areas where the competent vectors and other suitable environmental factors are existing [7].…”

Zika Virus (ZIKV) and its associated consequences remain vital public health challenge of international concerns. The current study was done to assess knowledge and attitudes towards ZIKV and the factors associated with good knowledge among medical students in King Abdulaziz University, Jeddah. A cross-sectional study was conducted among 426 students. They were selected through multistage stratified random sample method, 2016. A validated, confidential, interviewing questionnaire contained 25 knowledge and 10 attitude items was used. Descriptive and inferential statistics were done. Results revealed that Facebook was the commonest source of ZIKV information. About half of the participants correctly identified mosquito bites and vertical route as ZIKV transmission modes. However, smaller percentages recognized the sexual and blood transmission modes. Calculations of knowledge score revealed that 77.5%, 15.0%, and 7.5% of the participants obtained poor, fair, and satisfactory scores, respectively. Age, educational year and attending ZIKV training were significantly associated with good knowledge (p<0.05). Concerning attitudes, about half of the participants agreed that ZIKV could add new burden on healthcare system of the affected countries. Most of participants were interested in learning more about ZIKV, emerging diseases and travel epidemiology. In conclusion, medical students had limited knowledge about ZIKV, and good attitudes towards learning about it. Conduction of ZIKV educational programs, and development of courses about emerging disease epidemiology are required.

“…The results showed arguments that support (Franca et al, 2016;Guedes et al, 2016;Guo et al, 2016) or reject (Aliota et al, 2016b;Amraoui et al, 2016;Boccolini et al, 2016;Fernandes et al, 2016;HallMendelin et al, 2016;Huang Y.J. et al, 2016;Weger-Lucarelli et al, 2016;Hart et al, 2017) Culex vector competence. To understand so many disparate results, the protocols should be analyzed and compared taking into account several issues that include the virus-vector origin (geographical coherence), and virus and vector past history in the laboratory (number of passages/generations) that made them genetically quite different to the complex wild circulating ones (Berthet et al, 2014;Bennett et al, 2016;Chouin-Carneiro et al, 2016;.…”

Zika Virus: What Have We Learnt Since the Start of the Recent Epidemic?

Zika is a viral disease transmitted mainly by mosquitoes of the genus Aedes. In recent years, it has expanded geographically, changing from an endemic mosquito-borne disease across equatorial Asia and Africa, to an epidemic disease causing large outbreaks in several areas of the world. With the recent Zika virus (ZIKV) outbreaks in the Americas, the disease has become a focus of attention of public health agencies and of the international research community, especially due to an association with neurological disorders in adults and to the severe neurological and ophthalmological abnormalities found in fetuses and newborns of mothers exposed to ZIKV during pregnancy. A large number of studies have been published in the last 3 years, revealing the structure of the virus, how it is transmitted and how it affects human cells. Many different animal models have been developed, which recapitulate several features of ZIKV disease and its neurological consequences. Moreover, several vaccine candidates are now in active preclinical development, and three of them have already entered phase I clinical trials. Likewise, many different compounds targeting viral and cellular components are being tested in in vitro and in experimental animal models. This review aims to discuss the current state of this rapidly growing literature from a multidisciplinary perspective, as well as to present an overview of the public health response to Zika and of the perspectives for the prevention and treatment of this disease.

“…The magnitude of these neurological problems associated with ZVD outbreak of 2015 was so worrisome that the World Health Organization (WHO) in February 1, 2016 declared the outbreak a "PUBLIC HEALTH EMERGENCY OF INTERNATIONAL CONCERN", and activated an Emergency Incident Management System to handle international response to the outbreak [14]. The spread of this infection to countries where it was previously unknown was so alarming that in January 2017, mosquito-borne transmission of the infection had been reported in 75 countries across the globe, with 46 of these countries being in the Latin American and Caribbean zones [15] [16].…”

Zika virus is transmitted through the bite of infected Aedesa egypti, or Aedes albopictus mosquito, and re-emerged as a disease of global public health importance in March/April 2015 in Brazil. The objective of this study is to assess the formal education related pattern of awareness, and basic knowledge on Zika virus disease, among women visiting children immunization unit in a tertiary hospital, in Nigeria. Study was conducted in 2016/2017 with 256 randomly selected respondents. Semi-structured questionnaire was used in the cross-sectional study. Findings including 77.8% of respondents with postgraduate educational qualification were aware that there is a disease known as Zika Virus Disease (ZVD), 62.0% for tertiary education qualification, 53.8% for secondary education level, 20.0% for primary education level, while none of the three respondents that had no formal education were aware of ZVD. The level of awareness increased with increasing educational qualification. These findings were analyzed using the Likelihood Ratio which was calculated to be 28.329, with P-value of <0.001. Television was the commonest source of first ZVD information. Overall mean percentage knowledge level of the different educational groups revealed as followed; no formal education 22.2%, primary level 12.0%, secondary level 46.1%, tertiary level 54.4%, and postgraduate level was 51.5%. The mean for the stated scores was 37.2%. Students' T-Test at 95.0% confidence interval was 0.012, showing that the difference in the mean percentage scores between the groups was significant. Respondents with tertiary and postgraduate education qualifications recorded overall mean score above 50.0% each, while secondary, primary, and no for-How to cite this paper: Ndibuagu, E.O.
